Bert Vaux is primarily interested in phenomena that shed light on the
structure and origins of the phonological component of the grammar,
especially in the realms of psychophonology (language games, speech
errors, acquisition of first, second, and toy languages, development
of writing systems), historical linguistics (sound change,
reconstruction, evolution of language, Indo-European, Altaic, and
Northwest Caucasian languages), and sociolinguistics (dialectology,
microvariation, and nanovariation). He also enjoys working with native
speakers to document endangered languages, especially dialects of
Armenian, Abkhaz, and English.
